Labs that run
Water Cycle Lab Predict the next stage — evaporation, condensation, precipitation or collection — before the answer is revealed. Food Web Lab Sort producers from predators and predict the cascade when a species disappears. Logic Lab Meet AND, OR, NOT, NAND, NOR & XOR — set the switches, predict the bulb, then check your truth table. Matter Lab Heat or cool a real substance, then PREDICT its new state using its real melting and boiling points. Electric Circuit Lab Series vs parallel — when one bulb burns out, what happens to the other? Predict, then wire it. Buoyancy Lab Sink or float — by comparing densities, not weight. A heavy log floats; a tiny steel ball sinks. Shadow Lab Move the card, the wall or the lamp and predict the shadow: bigger, smaller, or which way it goes. Light travels in straight lines. Decay It 100× Predict how a hundred atoms spread out as they decay — run it once, then a hundred times, and watch the half-life appear.
